This invention relates to tabulating machines and more particularly tomeans for controlling the paper feed mechanism of such machines.

In Fig. 1 of the accompanying drawings a tabulating machine isillustrated having mechanism for feeding paper from a roll in such a waythat the paper is moved through the printing zone at intervalscorresponding to the completion of each account or the like, an amountwhich is complementary to the length of the account or the like. Thismechanism is fully disclosed in the co-pending application, Serial No.419,977, of Thomas and English, now Patent No. 1,896,983, dated February7, 1933.

The machine illustrated in Figure l is also provided with a cycliccontrol device comprising a threaded nut member rotated step by step oneach machine cycle, means operable by the nut member after apredetermined axial displacement to effect a predetermined operation inthe machine such as stopping or totalling, setting means determining the,extent of axial displacement of the nut member before the predeterminedoperation is effected and means whereby the nut member is automaticallyreset. This cyclic control device also is not claimed per se herein butis the subject of co-pending United States patent application Serial No.419,978, now Patent No. 1,938,228, to Thomas, dated December 5, 1933.

The present invention has for one of its objects to provide an operativeconnection between the aforesaid cyclic control device and the paperfeeding mechanism referred to above whereby said cyclic control devicecan be used to control the paper feed.

In order that the invention may be more clearly understood referencewill now be made to the accompanying drawings which show by way ofexample some preferred embodiments oi the present invention.

Figure 1 is an elevation of the tabulator showing the combined paperfeed mechanism and cyclic control device;

The invention is shown applied to the well known Powers tabulator. Inthe combination illustrated in Figures 1 and 2 the paper feed mechanismcomprises a gripper l carriedon a rocking shaft 2, carried by blocks 2aslidably supported on posts 3, carried by the head T of the tabulatingmachine above the carriage C thereof, the rocking shaft 2 beingconnected to one end of a lever 6 through a connecting rod 4. Therocking shaft 2 is connected to the rod 4 through toggle links 5 and 5a,the links 5a being pivoted to the block 2a at 5b so that as the rod 4moves up and down the toggles are contracted or straightened to closeand dopen the gripper.

The lever 6 is carried on a xed pivot 7 mounted on a bracket 8 carriedby the frame of the machine, and is rocked in any suitable manner, tocause the gripper to grip the paper by enforcing a longitudinaldisplacement of the connecting rod 4, and the consequential rocking ofthe shaft 2 carrying the gripper 1. The gripper is rst moved upwardlycarrying the paper with it and is lthen retracted downwardly withoutmoving the paper.

It is to be understood that during the tabulation of items the gripperis inactive and the paper is fed forward line by line by the platen Pbut is held frictionally by a device indicated at 9 so that a loop l0 ofpaper is formed between( the platen P and the gripper l. At the end ofthe tabulation of a group of items the machine automatically takes atotal by means not shown. In the total-taking cycle the gripper iirstvmoves upwards as already described and pulls the paper past the frictionholding device 9 thereby straightening out the loop 10. The gripper thencontinues its upward movement and pulls the paper through the platen toan extent Such that the total length of paper moved by the gripperequals the length of a, standard Sheet so that the head of the nextsheet is in position for printing at the commencement of the nexttabulating operation.

The lever 6 is slotted as indicated at 6a and passes over a pin llacarried on a disc 11 so that on rotation of the disc the lever 6 isoscillated about its pivot 7.

The disc 11 is provided at the back with a clutch device by means ofwhich the disc can be connected on occasion to power means whereby itcan be rotated. To this end the disc is provided with a plunger 12pressed by -a spring not shown into the path of an actuating arm 13fixed to a power shaft 14 on which the disc 11 is loosely mounted (seeFig. 2) so that the disc is rotated from the shaft by the agency of theIll constantly rotated actuating arm thereon engaging the spring pressedplunger 12 carried by the disc when the'plunger is standing in the pathof the arm.

When the machine is tabulating it is desired that the gripper deviceshall remain inoperative. Consequently, means are provided forwithdrawing the plunger 12 out of the path of the constantly rotatingactuating arm at each revolution of the disc 11. Such means may comprisea a trip member 15 having an inclined surface 16 adapted to engage witha projecting collar 17 on the plunger 12 when the trip member 15 isturned about its pivot 18 in a clockwise direction. Projecting into thepath of the trip member 15 is the nose 19 of a lever 20 pivoted at 21 sothat as long as the nose 19 remains in the path of the trip 15 thegripper device will remain inoperative. When the member 15 is releasedfrom the nose 19, the said spring forces the plunger 12 lengthwise and,by the collar 17 acting on the inclined surface 16, restores said member15.

The lever 20 may be operatively connected to the total taking mechanismin order that when a total is taken the nose 19 may be withdrawn fromthe path of the trip member 15 and the gripper device actuated. To thisend the lever 20 is connected (by means of an interponent 62 to bedescribed later) to a horizontal link 22 pivoted at one end 23 to an arm24 mounted ori` a shaft 25 and at the other end 26 to an arm 27 securedto a shaft 28 adapted to be oscillated from the total taking mechanism.

In addition to controlling the gripper device from the total takingmechanism it is desirable also to cause it to operate after apredetermined number of cycles of the machine has occurred. To this endthe cyclic control device now about to be described and forming thesubject matter of co-pending United States patent application Serial No.419,978 may be used.

Much of this cyclic control device is mounted on a xed plate and onanother fixed plate secured to the plate 100 in part by a post 101 Fig.5). In the latter plate there yis rigidly mounted a spindle 32 whichpasses through the plate 100 at which point, however, it is surroundedby a rotary sleeve 103, which sleeve is rotatable in the plate 100, Saidsleeve has fast thereon a ratchet wheel 31 engaged by a drive pawl 33and a retaining pawl 41, the feed of the ratchet being counter-clockwisein Fig. 5. Behind the plate 100 the sleeve 103 has coiled around it arestoring spring 106 secured at one end to a collar 107 on the end ofthe sleeve, and at the other end to the plate 100. The construction issuch that the ratchet wheel 3l and the sleeve are fed step by stepcounter-clockwise against the tension of this spring, and when the twopawls are lifted out of the ratchet, the latter will be rotated by thespring clockwise until arrested in initial position.

The drive pawl 33 is pivoted to a plate 34 which in turn is pivoted onthe sleeve 103 and is rocked by a long link 37 pivoted thereto at 36beneath the spindle 32. is guided for longitudinal motion on one of themain shafts 40 of the machine by the side of a cam 40a fast on saidshaft. A follower 38 mounted on the link 37 engages this cam, which thusreciprocates the link and, therefore, the plate 34 and pawl 33 once ateach cycle of the machine.

Projecting from the face of the ratchet wheel 31 are two posts 29aembracing between them the This link-has a slot by which it flat sidesof a member which includes a.nut 29 and a cam 30, said nut running on athreaded section of the spindle 32. This device 29, 30 rotates with theratchet wheel and is moved slowly along the spindle by the screw. Thecounterclockwise motion of the ratchet wheel feeds the nut towards saidratchet wheel. Its initial position may be determined in any suitableway. In the device shown in Patent No. 1,938,228 a drum 110, alsothreaded on the spindle 32, can be turned by a milled head 111 and gears112, and the devices which arrest the member 29, 30 in its initialposition are adjustably controlled by said drum. The construction issuch that any desired extent of feed, that is to say, feed correspondingto any desired number of cycles of the machine, can be measured'off forthe nut 29 by a suitable adjustment of the milled head 111. Thesedevices are not shown in detail, as they do not per se constitute anypart of the invention, and they may be of any suitable construction.

On the same shaft of the tabulator which effects the reciprocation ofthe sensing pin box, there is mounted an eccentric 113 controlling apitman 114 on which is mounted a plate 115. From said plate thereprojects a pivot pin 116 on which is pivoted a two-armed device 117, onearm of which is pivoted to a vertical link 45, which, at its lower end,has a slot 44a embracing a pivot 44 fast on the plate 100. Theconstruction is such that this link 45 is given an oscillation about thepivot 44 at each cycle of the machine.

On said pivot 44 there is also mounted another link 118 by means of aslot so that this link also may rock about the pivot and may slide upand down on it. To the upper end of link 118 there is rigidly riveted aplate 43, hereinafter called the obstructor arm an offset section ofwhich has a slot 120 embracing the same pivot pin 46 as the arm 117,said slot being vertical so that the plate 43 may slide up and down onthe pin or screw 46.

The link 37 which operates the pawl 33, has a longitudinal slot vbywhich it is guided'by a stud projecting from the plate 100. Pivoted onthis stud is a lever arm 48 normally drawn upward by a spring 121. Onthis lever arm is mounted a stud or follower roller 48a which is inposition to be engaged and depressed by the cam portion 30 of the'nut29. In the initial position of the parts, that is to say at thebeginning of a series of tabulations, the nut 29 has moved along thescrew away from the ratchet 31 to such an extent that in its rotation bysaid ratchet, cam 30 does not strike the stud 48a, but in the lastrotation the screw thread will have brought this cam so far toward theratchet wheel that the cam 30 will strike the stud and depress the lever48.

Means are provided whereby this results in a depression of the plate 43.from the link 45 just above the upper edge of the lever 48, and it isthis pin which normally holds the said link in its upper position. Thelink is connected with the lever 48 by a spring 45a so that when saidlever is depressed, the link follows it downward, which motion ispermitted by the slot 44a.

The link 118 also has a pin 122 which overlies the lever 48, and thislink is also connected with said lever by a spring so that when thelever is depressed the link 118 moves down with it and the plate 43 istherefore moved to a position low-` er than that shown in Fig. 5. InFig. 4 the normal or upper position of this plate is shown A pin 47projects in chain lines, and the depressed position in full lines. Theconstruction is such that when the plate 43 is in its upper position andis reciprocated by the eccentric 113 it passes over the extension 33a ofthe 'feed pawl 33, but when after a predetermined number of operationsof the machine it is moved to its lower position, as above described,then o'n its next reciprocation it strikes this extension and swings thepawl 33 out of engagement with the ratchet wheel. The holding pawl 41has an upward extension lying just behind the extension 33a, so thatthis pawl is also disengaged from the ratchet which is then free to turnclockwise. This it will immediately do driven by its spring 106 untilarrested by the adjustable devices controlled by the milled head lll.'Ihe extension 33a of the pawl 33 .is prolonged as shown at 33h toconstitute a finger piece by which the pawls may be released by hand.

In the Patent No. 1,938,228 this'mechanism is used for various purposes.

According to the present invention an operative connection is providedbetween the cyclic control device including the nut member 29 and thepaper feed mechanism including the gripper l previously described.

To this end a latch in the form of a claw 49 (Fig. 4) is provided overthe manually operable handle 33h on the pawl 33 of the cyclic controldevice, said latch 49 being pivoted at 50 to a lever 51 in turn pivotedat 52. The latch member 49 is provided with a pin 53 which stands in thepath of the obstructor arm 43 of the cyclic control device when thelatter is lowered into its operative position as indicated in full lineson Fig. 4, the inoperative position being indicated in chain lines.Consequently, when the oostructor arm 43 reciprocates it strikes the pin53 on the latch member 4 9, thereby moving the latch 49 bodily to theright in Fig. 4 thereby turning the lever 51 in an anti-clockwisedirection about its pivot 52. At the same time the latch 49 by engagingwith the handle 33h of the pawl 33 turns the pawl 33 aboutits pivot andraises it clear of the ratchet Wheel 31. Also the cranked portion 33a ofthe pawl 33 engages with the free arm of the detent 41 and turns thisabout its pivot thereby freeing the detent from the ratchet 31 andpermitting the latter to run back to its initial position under theaction of the coil spring previously referred to.

The movement of the lever 51 is transmitted through a connecting rod 54to a crank 55 on a small shaft 56 provided with a second crank 57 which,through the agency of link 58, rocks a bell crank 59 which may beoperatively connected with a control arm 60 connected to the lever 20below the pivot 21 of the latter. This lever 20, according to itsposition, controls the clutch for connecting the disc 11 of the longpaper feed to its source of power as previously described,

The connection between the arm 60 and the bell crank 59 is settable toproduce a variety of operations. Said bell crank has an ear 59a bent offtherefrom so that it can be inserted in an arc-shaped slot 60a in thearm 60.' The latter can be swung right and left so that in one positionthe ear 59a is in the slot and in the other position is out of it. Thefree end of the arm 60 is controlled by a guide in the form of a sort ofgate G having in it four notches in any one of which the arm 60 may lie,namely, two upper notches G1 and G2, and two lower notches G3 and G.When the arm rests in either of the notches G1 or G3 the slot 60aembraces the Year 59a and the link 60 and lever 59 are inoperativevconnection; but when the link engages either of the notches G2or G4 the link and lever are disconnected.

' The lever 20 has pivoted to its upper end an interponent 62 which isconnected by a link 61 with the arm 60 so that said interponent and armrock up and down in unison. When the link 60 is in one of the uppernotches Gl or G2 the interponent 62 stands just behind a pin 63projecting from the link 26, so that when said link is operated to takea total the lever 20 will be tripped and the long paper feed will beoperated; but when the link 60 is in one of the lower notches G3 and G4the interponent will stand below the pin 63, and the long paper feedmechanism will be out of the control of the total taking mechanism.

It will be perceived that different modes of operation may be obtaineddepending upon which of the four notches is occupied by the arm 60.

When the said arm is in the notch G2 the long paper feed mechanism willbe controlled by the total taking mechanism and not by the counters. Thegrippers 1 will be actuated to draw the paper up to the beginning of thenext bill after printing every total.

When the link 60 is in the lower notch G4 the long paper feed mechanismis disconnected both from the total taking mechanism and from thecounter. In such case the paper need not be led through the grippers 1,and the long paper feed will be out of use entirely. When thelink 60 isin the notch G3 the long paper feed willvoccur after the predeterminednumbers of cycles of the machine for which the counter has been set, andirrespective of totaltaking.

When the arm 60 is in the notchG1 the long paper feed will be under thejoint control of the total taking mechanism and the counter; that is tosay, the long feed will be imparted to the paper either at a totaltaking operation or after a predetermined number of cycles dependingupon which of these comes into operation first. If, for example, eachbill form is long enough for twenty-five lines of printing and thecounter is set accordingly then, if a particular invoice contains onlyseventeen items after which a total is taken, then on the taking of thetotal the lever 2O will be tripped and the gripper will feed themechanism up to the rst printing line of the next form. If, however, aninvoice contains thirty items, which is more than can be entered on oneform, then after the printing of the twenty-fifth item the counter willcause an actuation of the bell crank 59, arm 60 and trip lever 20 andthe gripper will draw the mechanism forward so that the twenty-sixth andsucceeding items will be printed on the next form. In these machines atotal will then automatically be taken which involves an actuation ofthe link 22, which through pin 63 and interponent 62 will actuate triplever 20, and cause a new form to be brought to printing position toreceive the next invoice.

It is necessary to reset the counter to its initial position When thelever 20 is tripped by the total taking mechanism so that the count willbegin afresh on the new invoice. When the lever 20 is rocked by thetotal taking mechanism as described, it moves the arm 60 rightward inFlg. 4 which in turn rocks the parts 57, 56, 55 clockwise, moves link 54toward the left and rocks lever 51 counter-clockwise. This lever has apin 51a projecting therefrom just beneath the hook 49 and acting whenthe parts are in normal position to hold said hook up out of engagementwith the arm 33h as shown in Fig. 4 so as not to interfere with theoperation of the ratchet 31 by the feed pawl 33. When on a total takingoperation the lever 51 is swung counter-clockwise, the ilrst part of itsmotion permits the hook to drop into engagement with the arm 33b and thelatter part of its motion causes said hook acting on said arm to rocksaid pawl 33, and with it, the holding pawl 44 out of engagement withratchet wheel, leaving the latter free to be rotated bacl: to itsinitial position by its spring 106. It has heretofore been explainedthat the counter automatically returns to its initial position when ititself causes an actuation of the paper i'eed mechanism.

The' arm 60 connected to the pivoted lever 20 may also be manuallypulled out to the right in Fig. 4 and latched in that position by meansof a notch 60e in the arm 60 engaging with the 'notch Gr4 in the gate,thus permanently disconnecting the pivoted lever 20 from the trip l5 onthe disc 1l and causing the gripper to operate on every cycle of themachine.

From the foregoing it will be understood that when the control arm 60 isin the notch Gl the operation of the gripper is controlled by the cycliccontrol device and by the total mechanism, and if operated by the totalmechanism the cyclic control device is reset.

In such arrangement therefore there cannot be more than a denite numberof lines in a predetermined interval on the printing sheet and as thereis a feeding of the paper after a total operation the first item in anyinterval is spaced equally from the first item in the previous inter-Val, and the following interval, even though no total taking operationis effected in every interval.

In the position G2 the control arm 60 sets the parts so `that thegripper is controlled by the total mechanism of the machine, but thereis no control from the cyclic control device.

With the control arm in the notch G3 operation of the gripper is solelycontrolled by the cyclic control device the total mechanism beingdisconnected from the gripper mechanism whilst if the control arm 60 isin notch G4 of the gate the gripper mechanism is entirely disconnected.
